other words, your house is on an island.

map_edit on - You can edit the map.

route_balloons on - An bubble appears on top of the
characters, and the bubbles show why they dont want to
go to work, or do as you say.

route_balloons off - The balloons dissapear.

autonomy # - Choose IQ for the sims. Write a number
between 1-100 instead of #.

For _really_ fast money:

First write the "rosebud" cheat in the box. Then after
that you press Ctrl + Shift + C again and write:
